im looking into this exhaust and comes with a k&n filter too.if you have this exhaust did it give you a noticeable power gain?dont care about the sound long as it works well.

You will need to rejet along with the filter and exhaust.

HMF makes a really good exhaust.I'd buy it if I hadn't made duals for mine.lol

My best friend has the HMF full set-up and it's really throaty in sound and it runs pretty good for a sport clutch. definitely noticable over stock I'v ridden it both ways.

I have the hfm sport exhaust system on my 250 ex. along with a k&n filter and have rejeted the carb for it and I like it a lot i noticed better power through out the rpm range, and the bike seems to have more torque now in first and second gear i love it. and it's loud when I hit the gas.

how much did you spend?

I have just the slip-on and it gave HUGE gains.

 

[Billy250X]

Yeah but you also have a 450r not a 250ex.LOL!!

 

[Redracer]

It's the same technology, just different bends

 

[t-rex]
